the class TestContainer method testEvictableWithBusyMp.

@Test

    assertTrue(poll(mp, o -> o.invocationCount == 2));
    // now kick off the evict in a separate thread since we expect it to hang
    // until the mp becomes unstuck.
    // this will allow us to see the evict pass complete
    final AtomicBoolean evictIsComplete = new AtomicBoolean(false);
    final Thread thread = new Thread(new Runnable() {

        }
    });
    thread.start();
    // now check to make sure eviction doesn't complete.
    // just a little to give any mistakes a change to work themselves through
    Thread.sleep(100);
    // make sure eviction didn't finish
    assertFalse(evictIsComplete.get());
    // this lets it go
    mp.latch.countDown();

    assertTrue(poll(evictIsComplete, o -> o.get()));
    Thread.sleep(100);
    assertEquals("activation count, 2nd message", 1, mp.activationCount);
